Mensa accepts, but does not administer IQ tests.
A young 12 year old just maxed out at 162 as highest score ever on Cattell according to article I just read. Is there a story about you?
No one knows about me by choice by myself and a recommendation by my employer. There are certain information about people which are not released for security reasons. BTW there are several people with IQs who are in the 200 - 240 range that you will never read nor hear about. Nearly all of us choose to be anonymous and for good reasons. It is really not important for you to know.
